BOSS is now shipping the new Micro BR Digital Recorder. The palmtop guitar companion and recording studio is only slightly larger than an iPod. The Micro BR offers the ability to load and play back MP3 files, time-stretch MP3s in real time without affecting pitch, has an onboard guitar multi-effects processor, built-in rhythm patterns, and offers 32 recording tracks (V-tracks) with four simultaneous playback tracks. USB compatibility allows loading or uploading of MP3 files for play-along, rehearsing, jamming, or data exchange with a computer. The recording media of choice is the internationally recognized Secure Digital (SD) Card which can be easily found in electronics stores across the country.
